For another example, the operator can divide the day into a plurality of different time periods according to the network usage status, and set different charging rates for different time periods. For example, set a higher rate during periods of heavy network (such as between 20:00 and 23:00 daily); set a lower rate during periods of idle network (such as between 6:00 and 8:00). Even free.

Abstract

Un mode de réalisation de la présente invention porte sur un procédé de facturation, un dispositif de facturation, un système de facturation et un dispositif d'authentification. Le procédé de facturation consiste à : recevoir une requête de trafic envoyée par le dispositif d'authentification conformément à une requête d'accès provenant d'un dispositif d'accès, la requête de trafic contenant le trafic demandé (202) ; lorsque le trafic actuellement disponible est inférieur au trafic demandé et l'intervalle de temps entre l'instant courant et le point de commutation de tarif de facturation ne dépasse pas un intervalle de temps préréglé, et si la condition d'exception de déconnexion forcée est satisfaite, notifier au dispositif d'authentification de renvoyer un trafic permis déterminé conformément au trafic actuellement disponible au dispositif d'accès, et notifier au dispositif d'accès, par le dispositif d'authentification, de renvoyer une autre requête de trafic lorsque le trafic permis sera atteint (204). Selon la solution technique décrite dans le mode de réalisation de la présente invention, lorsque le trafic disponible d'un utilisateur est insuffisant et est proche du point de commutation de tarif de facturation, l'opération de déconnexion d'utilisateur forcée peut être sélectivement exécutée selon des circonstances spécifiques de manière à ce que l'opération de déconnexion d'utilisateur forcée puisse satisfaire les exigences de la politique de facturation de plus en plus complexe d'un opérateur.
